Abstract
Description
本発明は、米びつ用防虫剤に関するものである。 The present invention relates to an insect repellent for rice vines.
従来より、米びつ用途、もしくは貯蔵穀物類の主害虫であるコクゾウムシ対策が種々提案されている。例えば、特開平６−３８６７８号公報に示されるように、アリシン、カプサイシン等を成分とする米の抗菌、抗カビ、防虫を目的とした品質保存剤が公知であり、特許第３４０９１７６号公報には、ペリラアルデヒドを主成分とする薬剤を含浸した液含浸部材からなる米びつ防虫具が、一方、特開平１１−２２２４０９号公報には、有効成分として天然物由来のティートリーオイル及び／又はパインオイルを含有してなるコクゾウムシ忌避剤が記載されている。
また、最近、ワサビ、カラシ、トウガラシ、ニンニク等を使用したコクゾウムシの忌避剤が米びつ用として多く市販されている。これらは、使用する薬剤が食品であるため薬害の心配はないが、忌避効果が弱く、効果を確保するには大量に使用する必要がある。また、匂いが強いため米への匂い移りが避けられず、しかも人に対して刺激があるという問題も有する。
Conventionally, various countermeasures have been proposed for rice vines or measures against weevil which is a main pest of stored grains. For example, as disclosed in JP-A-6-38678, a quality preservative for the purpose of antibacterial, antifungal, and insect-proofing rice containing allicin, capsaicin and the like is known, and Japanese Patent No. 3409176 discloses In addition, a rice vine insect repellent composed of a liquid impregnated member impregnated with a drug mainly composed of perilaldehyde, while JP-A-11-222409 contains a tea tree oil and / or pine oil derived from natural products as an active ingredient A weevil repellent is described.
Recently, many weevil repellents using horseradish, mustard, pepper, garlic and the like have been marketed for rice. Since these drugs are foods, there is no worry of phytotoxicity, but the repellent effect is weak and it is necessary to use a large amount to ensure the effect. Moreover, since the smell is strong, the odor transfer to the rice is inevitable, and there is also a problem that the person is stimulated.
本発明は、コクゾウムシに代表される食品害虫に対する忌避効果並びに防虫効果と人畜に対する安全性に優れ、使い易く実用性の高い米びつ用防虫剤を提供することを目的とする。 An object of the present invention is to provide an insect repellent for rice vines which is excellent in repellent effect against food pests represented by weevil, insect repellent effect and safety against human livestock, and is easy to use and highly practical.
本発明は、以下の構成が上記目的を達成するために優れた効果を奏することを見出したものである。

(4) A fibrous carrier carrying 0.1 to 100 mg / cm 2 of p-menthane-3,8-diol is housed in a breathable container, and this breathable container has a means for fixing to the rice bin. The insect repellent for rice vines according to any one of (1) to (3).
本発明の米びつ用防虫剤は、コクゾウムシに代表される食品害虫に対する忌避効果並びに防虫効果と人畜に対する安全性に優れ、米への匂い移りがなく、使い易いのでその実用性は極めて高い。 The insect repellent for rice vines of the present invention has excellent repellent effect against food pests represented by weevil weevil, insect repellent effect and safety for human livestock, has no odor transfer to rice, and is easy to use, so its practicality is extremely high.
本発明の米びつ用防虫剤は、防虫成分として、ｐ−メンタン−３，８−ジオールを含有する。ｐ−メンタン−３，８−ジオールは、レモンユーカリの精油に含まれる物質で、天然由来成分であっても合成品のいずれであってもよい。ｐ−メンタン−３，８−ジオールには、立体構造に基づくトランス体とシス体が存在するが、本発明においては、両者の異性体の任意の割合の混合物を使用することができる。本化合物については、蚊などの飛翔害虫用忌避剤の忌避成分として公知であるが、コクゾウムシに代表される食品害虫に対する防虫効果についてはこれまで検討された報告はない。 The insect repellent for rice vines of the present invention contains p-menthane-3,8-diol as an insect repellent component. p-menthane-3,8-diol is a substance contained in the essential oil of lemon eucalyptus and may be either a naturally derived component or a synthetic product. In p-menthane-3,8-diol, there exist a trans isomer and a cis isomer based on a steric structure, but in the present invention, a mixture of both isomers in any ratio can be used. Although this compound is known as a repellent component of a repellent for flying insect pests such as mosquitoes, there has been no report to date regarding the insect repellent effect against food pests represented by the weevil.
しかるに、本発明者らは、この化合物のコクゾウムシ等に対する防虫効果を鋭意検討し、試験の結果、テルペン系化合物のなかでは特に優れた忌避効果ないし防虫効果を奏することを見出した。そして、この化合物は人畜に対して安全性が高く、匂いも弱いことから本用途に極めて有用であることを実証し、本発明を完成するに至ったものである。 However, the present inventors diligently investigated the insect repellent effect of this compound against weevil etc., and as a result of the test, they found that the terpene compound exhibits particularly excellent repellent effect or insect repellent effect. And since this compound is highly safe for human livestock and has a weak odor, it has been proved that it is extremely useful for this application, and the present invention has been completed.
本発明では、通常上記ｐ−メンタン−３，８−ジオールに各種の成分を加えて防虫組成物を調製し、これを種々の形態の米びつ用防虫剤に適用する。ｐ−メンタン−３，８−ジオールの米びつ用防虫剤全体量に対する配合量は、米びつ用防虫剤の形態によっても異なるが、米びつの容量として１０Ｌ当たり０．０２〜１．０ｇ程度に設定するのが好ましい。０．０２ｇ未満であると防虫効果が十分でなく、一方１．０ｇを超えるとベタつき感が出るなど実用的でない。 In the present invention, an insect repellent composition is usually prepared by adding various components to the above-mentioned p-menthane-3,8-diol, and this is applied to an insect repellent for various forms of rice. The blending amount of p-menthane-3,8-diol with respect to the total amount of the insecticide for rice vines varies depending on the form of the insecticide for rice vines, but the capacity of rice vine is set to about 0.02 to 1.0 g per 10 liters. Is preferred. If it is less than 0.02 g, the insect repellent effect is not sufficient, while if it exceeds 1.0 g, it is not practical, such as a sticky feeling.
本発明の米びつ用防虫剤には、上記ｐ−メンタン−３，８−ジオールとともに植物由来消臭成分を配合するのが好ましい。このような植物抽出物としては、イネ科、ツバキ科、イチョウ科、モクセイ科、クワ科、ミカン科、キントラノオ科、カキノキ科の中から選ばれた一種以上を用いるのが適当であり、緑茶抽出物や柿抽出物が代表的である。なお、植物由来消臭成分の配合量は、ｐ−メンタン−３，８−ジオールに対し、０．０１〜０．１倍量程度で十分である。
植物抽出物の成分として知られる、例えばポリフェノール類は、消臭成分として公知であるが、本発明の米びつ用防虫剤において、ｐ−メンタン−３，８−ジオールの効力増強成分として作用するという知見は全く新規なものである。その理由として、防虫成分が揮散する際に何らかの相互作用を及ぼしているものと推定される。
It is preferable to mix a plant-derived deodorant component with the p-menthane-3,8-diol in the insect repellent for rice vines of the present invention. As such a plant extract, it is appropriate to use one or more selected from the family Gramineae, Camelliaaceae, Ginkgoaceae, Oleaceae, Mulberry, Citrus, Kintranoaceae, Oysteraceae, and extract green tea. The product and the cocoon extract are typical. In addition, about 0.01-0.1 times amount is sufficient with respect to p-menthane-3,8-diol as the compounding quantity of a plant-derived deodorant component.
Known as a component of a plant extract, for example, polyphenols are known as deodorizing components, but in the insect repellent for rice vines of the present invention, the knowledge that they act as potentiating components of p-menthane-3,8-diol Is completely new. The reason is presumed to have some interaction when the insect repellent component is volatilized.

Further, examples of the gelling agent used for preparing the gel-like body include carrageenan, xanthan gum, gellan gum, gelatin, aluminum octylate, 12-hydroxystearic acid and the like.
本発明の米びつ用防虫剤は、上記防虫組成物を固体担体に含浸又は保持させたものを米びつ内に設置し、固体担体から防虫成分を揮散させる方式が好ましい。固体担体としては、パルプ、リンター、レーヨン等の繊維質担体、ケイ酸塩、シリカ、ゼオライト等の無機多孔質担体、トリオキサン、アダマンタン等の昇華性担体等があげられる。好ましくは、ｐ−メンタン−３，８−ジオールを０．１〜１００ｍｇ／ｃｍ２担持させた繊維質担体を通気性容器に収納し、この通気性容器を適当な固定手段を用いて米びつの上蓋の裏に固定したり、米の中に埋設するか、あるいは表面に置くようにすればよい。 As the insect repellent for rice vines of the present invention, a method in which the above insect repellant composition is impregnated or held in a solid carrier is placed in the rice jar and the insect repellant component is volatilized from the solid carrier. Examples of the solid carrier include fibrous carriers such as pulp, linter and rayon, inorganic porous carriers such as silicate, silica and zeolite, and sublimable carriers such as trioxane and adamantane. Preferably, a fibrous carrier carrying 0.1 to 100 mg / cm 2 of p-menthane-3,8-diol is housed in an air permeable container, and this air permeable container is covered with an upper lid of rice using appropriate fixing means. It can be fixed to the back of the rice, buried in rice, or placed on the surface.
通気性容器の形状や構成は何ら限定されないが、例えば、開閉可能な米俵状の通気性ケース内にマット挟持部材を設置し、これに防虫組成物含浸パルプ製マットを挟設してなるものや、防虫組成物含浸パルプ製マットを収納した扁平状の通気性ケース、あるいは、紙、織布、不織布、多孔シート等を用いた袋状の通気性容器に防虫組成物含浸パルプ製マットを収納してなるものがあげられる。 The shape and configuration of the breathable container are not limited at all, but, for example, a mat holding member is installed in a rice straw-shaped breathable case that can be opened and closed, and a mat made of pulp impregnated with an insect repellent composition is sandwiched between them Or a flat air-permeable case containing an insect repellent composition-impregnated pulp mat, or a bag-like air-permeable container using paper, woven fabric, nonwoven fabric, porous sheet, etc. What can be made.
このようにして得られた本発明の米びつ用防虫剤を、米びつ内に設置すれば、コクゾウムシ、カツオブシムシ、チャタテムシ、シバンムシ、ゴキブリ、アリ類等の食品につく害虫はもちろん、蚊類、蚋、ユスリカ類、ハエ類、チョウバエ類、イガ類などの各種害虫に対して１ケ月ないし２ケ月間の長期間にわたり実用的な防虫効果を奏するものである。そして、本発明で防虫成分として用いるｐ−メンタン−３，８−ジオールは、従来のワサビ、カラシ、ショウガやトウガラシ等に較べて匂いが極めて弱く、米への匂い移りもほとんどないのでその実用性は極めて高い。 If the insecticide for rice vines of the present invention thus obtained is installed in the rice vine, not only pests on foods such as weevil, cutlet worm, scallop, beetle, cockroach, ants, but also mosquitoes, moths, chironomids It exhibits a practical insect repellent effect over a long period of one to two months against various pests such as mosses, flies, butterflies and moths. In addition, p-menthane-3,8-diol used as an insect repellent component in the present invention has a very weak odor compared to conventional wasabi, mustard, ginger, pepper, etc., and has almost no odor transfer to rice, so its practicality. Is extremely expensive.
次に具体的な実施例に基づき、本発明の米びつ用防虫剤について更に詳細に説明する。 Next, based on a concrete Example, the insecticide for rice vines of this invention is demonstrated in detail.
大きさが３×７ｃｍで厚さ１ｍｍのリンター製マットに、ｐ−メンタン−３，８−ジオールを２１０ｍｇ、緑茶エキスを６ｍｇ、及び灯油（脂肪族炭化水素系溶剤）を２０ｍｇ含有させ、このマットを開口部を有する扁平状のポリエステル製容器（米びつの上蓋の裏に固定用の両面テープ付き）に収納して、本発明の米びつ用防虫剤を調製した。
この米びつ用防虫剤を米びつ（容量：１０Ｌ）の上蓋の裏に固定して使用したところ、およそ１ケ月間にわたり、米びつ内でコクゾウムシ、カツオブシムシ、チャタテムシ、シバンムシ、ゴキブリ等を見かけることがなかった。
A linter mat with a size of 3 x 7 cm and a thickness of 1 mm contains 210 mg of p-menthane-3,8-diol, 6 mg of green tea extract, and 20 mg of kerosene (aliphatic hydrocarbon solvent). Was stored in a flat polyester container having an opening (with a double-sided tape for fixing on the back of the upper lid of the rice bottle) to prepare the insecticide for rice bottle of the present invention.
When this insecticide for rice was fixed and used on the back of the upper lid of rice (capacity: 10 L), weevil, cutworm, scallop, hornworm, cockroach, etc. were not found in the rice for about one month.
［殺虫効力試験］
実施例１に準じて、表１に示す各種米びつ用防虫剤を調製し、容量が約６Ｌの密閉容器の中に入れた。コクゾウムシ及びシバンムシ成虫を各３０匹投入し、７日後の致死率を求めたところ、表１の如くであった。
[Insecticidal efficacy test]
In accordance with Example 1, various rice insect repellents shown in Table 1 were prepared and placed in a sealed container having a capacity of about 6 L. When 30 weevil and adult beetle were introduced and the mortality after 7 days was determined, it was as shown in Table 1.
試験の結果、本発明の米びつ用防虫剤は、防虫成分として配合したｐ−メンタン−３，８−ジオールの作用に基づき、コクゾウムシ及びシバンムシ成虫に対して従来のワサビ成分やトウガラシ成分に較べて優れた殺虫効力を示し、ｐ−メンタン−３，８−ジオールの高い忌避効果を加味すると、食品につく害虫の防虫剤として実用性の高いことが認められた。また、緑茶エキスや柿抽出物の植物由来消臭成分を配合することによって、殺虫効力が向上することも明らかとなった。
さらに、いずれも火気に対する危険性が低く使用性の面でも優れたものであった。
これに対し、比較例に示すように、同じテルペン系化合物のマイヨール、あるいは忌避成分として一般的なチモールは、その殺虫効力が低いうえ匂いが強く米びつ用防虫剤の防虫成分としては不適であった。
As a result of the test, the insect repellent for rice vine according to the present invention is superior to conventional wasabi and capsicum components against the weevil and the beetle based on the action of p-menthane-3,8-diol blended as an insect repellent component. In view of the insecticidal efficacy, and taking into account the high repellent effect of p-menthane-3,8-diol, it was confirmed that it was highly practical as an insect repellent for food pests. Moreover, it became clear that insecticidal efficacy improves by mix | blending the plant-derived deodorant component of a green tea extract or a persimmon extract.
Furthermore, all of them were low in danger to fire and excellent in terms of usability.
On the other hand, as shown in the comparative examples, the same terpene compound mayol or thymol, which is a general repellent component, has a low insecticidal effect and has a strong odor and is not suitable as an insect repellent component for rice vest repellents. .
［匂いの移行試験］
米びつ（容量：１０Ｌ）の中に米を入れ、その上に実施例２に準じて調製した米びつ用防虫剤を置いた。５日後、米びつ用防虫剤を取り除き、その周囲の米へ匂いがどの程度移ったかに付き、モニター１０人による官能試験を行った。その結果を表２に示す。
[Odor transfer test]
Rice was put into the rice bin (capacity: 10 L), and an insecticide for rice bin prepared according to Example 2 was placed thereon. After 5 days, the insecticide for the rice vine was removed, and how much the odor moved to the surrounding rice was subjected to a sensory test with 10 monitors. The results are shown in Table 2.
試験の結果、天然由来のｐ−メンタン−３，８−ジオールを防虫成分とする本発明の米びつ用防虫剤は、米への匂い移りがなく、しかも人畜への毒性が非常に低いのでその実用性は極めて高い。
一方、ワサビ成分やトウガラシ成分は、匂いが強いため米への匂い移りが避けられず、また人に対して刺激があるという難点を有する。
As a result of the test, the insect repellent for rice vines of the present invention containing p-menthane-3,8-diol derived from nature as an insect repellent component has no odor transfer to rice and is extremely low in toxicity to human livestock. The nature is extremely high.
On the other hand, the wasabi component and the pepper component have a strong odor, so that the odor transfer to the rice cannot be avoided, and there is a problem that the human is irritating.
本発明は、米びつ用防虫剤だけでなく、広範な害虫防除分野において須らく利用可能である。
The present invention can be used not only for insecticides for rice vines but also in a wide range of pest control fields.
